It is used in the constructor to initialize the class data members.
without it your code will give error.

Hello @Satyamcoder,

It seems like if you have not understood the concept of ‘this’ pointer.

this is used to prevent the name conflict inside the class.

When do you need “this”?
Suppose, the name of the parameter passed accepted by the member function and the class data member is the same.
Then, this is used to distinguish the data member from the parameter.

Example:
class node{
public:
int data;
node * next;
node(int data){
data = data; // this will cause warning/error
//Thus to avoid this we use this pointer as
this->data=data;
}
};

Hope, this would help.
Give a like if you are satisfied.
